Biphasic Clinical Course of Pediatric Cytomegalovirus‐Associated Immune Thrombocytopenia: Early Poor Treatment Response but Favorable Long‐Term Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

Ink Droplet Position Compensation Based on Extended State Observer

International Journal of Automation Technology, 2010
The parabolic droplet trajectory in inkjet printing causes errors between actual position and expected positioning, deteriorating printing quality in highspeed printing. To improve printing quality and increase printing speed, an accurate firing time estimation method is proposed to compensate the droplet position error.

Enhancing Station-Keeping Control With the Use of Extended State Observers [PDF]

Frontiers in Applied Mathematics and Statistics, 2018
Recently there has been a resurgence of interest in missions to the moon and a major challenge of such missions is to provide a continuous communication between the Earth and the Moon's far side. Orbits around the L2 Earth-Moon Lagrange point have been a topic of interest in this field due to their potential for constant communication with both the ...

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...
